We always put the version number in an EV. App has chance to update version, and the value in EV need to sync with App version. I'm creating a utility to check and update App version, but the problem is that I cannot find a way to update the value in EV by BluePrism. Is there any solution to change the EV value automatically?

However, if your utility is reading the version number then you could run and store that value at start up and then feed the version number into the launch path of the App-V application.
